Abstract, Nectadrin, the cell surface glycoprotein recognized by the novel mAb 79, was found to be immunologically identical to the heat-stable antigen (HSA). It is a glycoprotein with a polypeptide core of only 30 amino acids and a very high carbohydrate content

This paper discusses data commonly used to study scientific cooperation, especially over the last three decades. Among the extensive bibliography using these data, our selection of articles highlights geographical levels most used to study "Worlds" of Scientific Cooperation in order to outline the advantages and limits of such a choice. Generally, the articles examined here do not take into account changes undergone by spatial units over time, such as modifications in weight and in the centrality index. These articles also tend to focus on key scientific fields such as nanotechnology. Very few studies examine small scientific communities such as the "DNA Transcription and Repair Group", even from a sociological viewpoint. After focusing on the publishing locations of the Group's first papers, we will define the field's trajectories over time by trying to answer questions such as "How does this small community's network evolve?" "Are the original locations still central to the evolving network?" This case study of the "Worlds" of Scientific Cooperation leads to questions such as "Are scientific activities substantially different from economic activities, such as the flow of finance or goods?" "What can a multi-level approach to Scientific Cooperation offer?" Minimize

This article aims to explain the current state of DNA Repair studies' global geography by focusing on the genesis of the scientific community. Bibliometric data is used to localize scientific activities related to DNA Repair at the city level. The keyword "DNA Repair" was introduced first by American scientists. It started to spread after 1964 that is to say, after P. Howard-Flanders (Yale University), P. Hanawalt (Stanford University) and R. Setlow (Oak Ridge Laboratories) found evidence for Excision Repair mechanisms. It was the first stage in the emergence of an autonomous scientific community. In this article, we will try to assess to what extent the geo-history of this scientific field is determinant in understanding its current geography. In order to do so, we will localize the places where the first "DNA Repair" publications were signed fifty years ago and the following spatial diffusion process, which led to the current geography of the field. Then, we will focus on the evolution of the research activity of "early entrants" in relation to the activity of "latecomers". This article is an opportunity to share with DNA Repair scientists some research results of a dynamic field in Science studies: spatial scientometrics Minimize

This article presents the speech understanding and dialog system EVAR and concentrates on the linguistic processing of the system. The task of EVAR is to lead an information retrieval dialogue about the German InterCity train system. The linguistic knowledge is uniformly represented in a semantic network structure. The knowledge base is well structured following the layered linguistic model. Interface to the speech recognition is the level of word hypotheses. The control algorithm is independent of the application and allows to alternate dynamically between the two fundamental control strategies top-down and bottom-up. The linguistic knowledge represented in the system is used to control the recognition phase and for the understanding phase. The system can handle defect input due to recognition errors. Results are presented for speaker-dependent and multi-speaker versions of the recognition module. Minimize
